Heritable epigenetics (Introduction)
Alternative splicing of exons changes the meaning of simply expecting one gene, one protein. By splicing exons together and removing the introns taht are inbetween, the genome can make anyting, even different species. Did evolution make this mechanism as life developed or was the splicosome there from the beginning, and is the source of complexification? I have predicted we would find such a mechanism? It is an easy jump for me to say God created the genome to act this way "After analyzing vast amounts of genetic data, the researchers found that the same genes are expressed in the same tissue types, such as liver or heart, across mammalian species. However, alternative splicing patterns—which determine the segments of those genes included or excluded—vary from species to species. "The core things that make a heart a heart are mostly determined by a heart-specific gene expression signature. But the core things that make a mouse a mouse may disproportionately derive from splicing patterns that differ from those of rats or other mammals" says Chris Burge, an MIT professor of biology and biological engineering, and senior author of a paper on the findings in the Dec. 20 online edition of Science."- Read more at: http://phys.org/news/2012-12-evolution-alternative-splicing-rna-rewires.html#jCp
